In order to guarantee their normal reliable communication, a kind of anti-jamming communication system - frequency hopping communication system arises at the historic moment, it has good anti-interference performance and multiple access network performance, not only has been widely applied in military communication, and is closely related to our daily life, has been widely used in civil mobile communication, such as GSM, HomeRF (RF) family, Bluetooth (Bluetooth) in the application of the frequency hopping technique. To analyze the anti-jamming capability of FH communication system, the hardware realization of frequency hopping communication is difficult, so this topic is based on Simulink to realize the frequency hopping communication system. This paper mainly introduces the basic principle of frequency hopping technique, composition, characteristics, and some key technologies involved. Using Simulink to build the simulation model of frequency hopping communication system, and mainly analyzes the anti-jamming performance of frequency hopping communication system. The simulation results show that the anti-interference ability of frequency hopping communication is very prominent. Key words: frequency hopping; Simulink; Anti-interference; 桂林电子科技大学毕业设计（论文）报告用纸
